Back on board

Engineers and crew aboard R/V Oceanus work to recover a deep-ocean
mooring
in the northwest tropical Atlantic in summer 2008. The mooring
recovery/deployment cruise, led by physical oceanographer Al Plueddemann, allowed scientists to retrieve long-term
data on the ocean and atmosphere collected by instruments fixed to a
mooring line stretched between the
surface and the seafloor—in this case, between 3,000 and 5,000 meters
deep. Data on salinity, temperatures, currents, acoustic data, and
atmospheric measurements all contribute to an understanding of how the upper ocean and atmosphere interact.
